It's worth it to me (#623). I use Evernote pretty heavily, but there are times where paper wins out (i.e. dead batteries and meetings where being on a phone/tablet could be frowned upon).
What I also enjoy about this idea is that it is like a physical version of Paper By 53. Although now instead of emailing Evernote my sketches via paper I can now snap a picture from Evernote itself. Seems like an interesting product tie-in that has me wanting it more than I want money.
